ABSTRACT
Objective: To evaluate the risk factors for contrast-induced nephropathy (CIN) in patients of acute coronary syndrome (ACS) with normal or slightly impaired renal function after percutaneous coronary intervention (PCI). Methods: A total of 254 consecutive ACS patients with normal or slightly impaired renal function received PCI in the Second Artillery General Hospital from 2013-06 to 2015-06 were retrospectively studied. All patients had eGRF≥60 ml (min?1.73 m2) and they were divided into 2 groups:CIN group, the patients with serum creatinine increased by 0.5mg/dl (44.2μmol/L) or elevated to 25%higher than the baseline, n=23;Non-CIN group, n=231. The basic condition with laboratory tests, operative indexes were recorded and eGRF value were calculated in all patients. Results: There were 9%(23/254) patients suffered from CIN after PCI. Multivariate regression analysis indicated that emergent PCI (OR=0.370, 95%CI 0.060-2.297), increased plasma level of NT-proBNP (OR=4.209, 95%CI 1.202-14.742) and without pre-operative aspirin administration (OR=7.950, 95%CI 1.108-57.034) were the clinical risk factors for post-operative CIN occurrence. Conclusion: Emergent PCI, higher plasma level of NT-proBNP and no pre-operative aspirin administration were the risk factors for CIN occurrence in ACS patients with normal or slightly impaired renal function after PCI.
ABSTRACT
Objective: To explore the relationship between the ratio of neutrophil/lymphocyte (NLR) and in-hospital major adverse cardiac events (MACE) in patients with acute ST-elevation myocardial infarction (STEMI) at early admission. Methods: A total of 420 acute STEMI patients admitted and received primary PCI in our hospital from 2010-01 to 2014-12 were retrospectively studied. The patients were divided into 2 groups:In-hospital MACE group, n=47 and Normal discharged group, n=373. Uni-and multivariate analyses were conducted to assess whether high NLR is the independent predictor for in-hospital MACE occurrence. Results: Univariate regression analysis indicated that the occurrence rate of in-hospital MACE in high NLR patients were higher than those in low NLR patients (OR=3.19, 95%CI 1.55-2.65, P=0.012). Multivariate regression analysis showed that high NLR was the independent risk factor for in-hospital MACE occurrence in STEMI patients (OR=3.05, 95%CI 1.59-10.54, P=0.015). Conclusion: High NLR is the independent risk factor for in-hospital MACE occurrence in STEMI patients at the early admission.
ABSTRACT
Objective To compare the effects of levosimendan (Levo) and recombinant human brain natriuretic peptide (rhBNP) in patients with acute decompensated heart failure (ADHF). Methods Seventy-five patients were included into this randomized positive-controlled and parallel-group study to receive either Levo (Levo group), rhBNP (rhBNP group) or dobutamine therapy (control group). Heart rate, respiratory rate, 24-hour urine volume,improvement in six-minute walk-test after 72-h treatment were compared between three groups. The blood level of BNP and values of left ventricular end dia?stolic diameter (LVEDD) and left ventricular ejection fraction (LVEF) after one-week treatment were compared between three groups. Results After 72-h treatment, heart rate and respiratory rate were significantly decreased, and 24-hour urine volume, six-minute walk-test were significantly increased in three groups (P0.05), but the LVEDD was improved barely (P>0.05). The improvements were more significant in Levo group and rhBNP group compared to those of control group (P<0.05). There were no significant differenc?es in improvements between Levo group and rhBNP group. The common adverse reactions were hypotension and ventricular premature beats. There were no significant differences in adverse event rates between three groups (P<0.05). Conclusion As compared with dobutamine, Levo and rhBNP have optimized efficacy, fewer side effects and good safety in the treatment of ADHF. They are worth of clinical application.
ABSTRACT
Objective To analyze the risk factors of paroxysmal atrial fibrillation (PAF) in very olderly hypertensive patients. Methods According to the electrocardiograph (ECG) and history data, two hundred and six older old-hypertensive patients were divided into PAF group (n=66) and sinus rhythm (SR) group (n=140). Data of age, gender, body mass index (BMI), the use of angiotension-converting enzyme inhibitors (ACEIs), angiotensin receptor blockers (ARBs) and statin drug history, 24-hour ambulatory blood pressure monitoring (ABPM), echocardiography, pulse wave velocity (PWV), blood lipid profile and renal function were recorded in two groups. Logistic regression analyses of the relevant factors were compared between groups. Results Data of age, the diameter of the left atrium (LAD), the 1eft ventricular mass index (LVMI) and the PWV were significantly higher in PAF group than those of SR group [(88.92±3.42) years old vs. (86.36±4.67) years old, (39.00±6.66) mm vs. (33.54±7.77) mm, (132.49±14.83) g vs. (119.00±11.35) g, (13.45±4.85) m/s vs. (9.89±2.74) m/s, respectively]. Values of three acyl glycerin (TG), blood pressure smoothing index (SI) were lower in PAF group than those of SR group [(1.33±0.91) mmol/L vs. (1.95±1.29) mmol/L, 0.75±0.06 vs. 0.79±0.04, respectively]. Results of two classification Logistic regression analyses showed that the reduced SI, the enlarged LAD and LVMI and the increased PWV were the risk factors of PAF in very olderly hypertensive patients. Conclusion Unstable blood pressure, left atrial enlargement, left ventricular hypertrophy and arterial stiffness are the risk factors of PAF in very olderly hypertensive patients.

ABSTRACT
Conditioned fear and its abnormal extinction are involved in the psychopathology of anxiety disorders, such as posttraumatic stress disorder (PTSD). Cognitive enhancing agents have been demonstrated to alter fear extinction in many animal research literatures. The present review has examined the pharmacological role of gamma-aminobutyric acid (GABA), glutamatergic, cholinergic, adrenergic, dopaminergic, and cannabinoid as well as compounds able to alter the epigenetic and neurotrophic mechanism in fear extinction, highlighting great hope for the future treatment of anxiety disorders with new agents based on the fear extinction.
